it really doesnt matter, when 3.0 came out wotlk was 4 weeks away. Raids in wotlk(25s) wont be that easy, as blue already stated it(in the thread about tanking being too easy at 70). Im hoping that most of t8/9 content at least for first few months will be as hard as sunwell used to be. On beta all t7 content is pretty damn easy too, I predict my guild clearing all t7 by 17th-18th, maybe faster..
